Malignant melanoma resection and reconstruction with the first manifestation of lumbar metastasis: A case report

Figure 1 Magnetic resonance imaging and computed tomography of the patient's lumbar spine. A: In the sagittal position, tumors may be compressing the spinal cord; B: The transverse view shows that the right spinal cord is compressed by a tumor; C: The transverse position shows destruction of the right pedicle and vertebral body; D: In the sagittal position, the posterior side of the spine is destroyed by tumors.

Figure 2 Histopathology of lumbar melanoma. A: Vertebral biopsy shows some tumor cells; B: After vertebral body resection, a large number of tumor cells can be seen.

Figure 3 Patient intraoperative and postoperative follow-up results. A and B: During the operation, the lumbar vertebra 2 was completely removed; C and D: The anteroposterior X-ray film of the lumbar spine 2 wk after surgery revealed that the 3D-printed prosthesis was well attached to the upper and lower vertebral plates; E and F: Six months after surgery, a lumbar computed tomography revealed that the boundary between the three-dimensional (3D)-printed prosthesis and the adjacent vertebral body had disappeared and bone trabeculae had grown in.
